First step new reagents prepared. The reagents were diagnosed in the prepared through several known techniques such as NMRR, FT-IR, CHNS and Mass. Also, the study was complexes of the prepared reagent. A set of metals has been used by the studied optimal conditions were studied. In the follow step a cloud end confinement modus operandi was presented for the pre-concentration of down a bear ion in various samples. Investigate complexity by Hexyl carbamodithioate analyte ion are quantitatively extracted in (TritonX-114) following centrifugation. 1.0 mol/ L HCl nitric sharp in CH3OH was additional to the (surfactant-rich) steady old-fashioned previous to its analysis by (FAAS). (Triton X-114) and HCl and centrifuge rate, definite temperature and time were optimized. Recognition court for touch on ion was 0.091 ngmL−1. Limit of quantity (LOQ) (0.305 ng/ml), sensitivity (2×1−4) under optimum experimental conditions. The approach advanced has been successfully carried out to the determination of lead ion trace stages in electric energy plant water samples. [ABSTRACT FROM AUTHOR]

The goal of this study is to create a new gadget that will be a breakthrough in medical technology by employing a high-precision error-correcting mechanism. This strategy is used to take advantage the device's ECG great accuracy. A portable device that already exists is compared to the newly invented gadget. This study proposes a portable gadget that is produced as a result of the Arduino software's mistake correcting. We can make do with a low-cost AD8232 sensor. Three locations on the electrode patch single lead sensor AD823 create the Einthoven triangle. The AD8232 sensor is the key component that processes the voltage received from the electrodes attached to the body to listen to the pulse. The text of the paper shows how to use the AD8232 sensor to collect ECG signals and connect them to an Arduino Uno. The Arduino serves as a sampler as well as an A/D converter (ADC). Once the sensor is connected to the Arduino, the electrodes are attached to the sensor and then to the patient's body to collect samples. The information is compared to standard ECG signals. The ECG signal includes one full heartbeat, represented as a collection of critical points in the ECG. By noting certain intervals and comparing them to standard readings, these PQRST points are utilized to identify ECG irregularities or arrhythmias. One of the features of the device is to display the reading of the electrocardiogram on the computer screen with extreme accuracy, and this benefits the specialist doctor during the diagnosis. In addition, three electrodes were used instead of the 12 electrodes normally used. [ABSTRACT FROM AUTHOR]
